A series of tests were previously conducted to determine the strength and failure modes of various heavy truck cargo anchor points. The tests covered a range of types and grade of anchor point, for various tiedown attachments, and a number of pull directions. Most test articles were strain-gauged to provide insight into their structural performance, and most were tested to failure. The results showed a very wide range of load capacity, both between and within types of anchor point. In most cases, the load capacity also varied significantly with the direction of loading. Most anchor points were found to start to yield at quite low loads, and deformed substantially as the test progressed. Limited finite element analyses compared well with corresponding strain data from tests. This work led to recommendations that cargo anchor points should be designated on heavy trucks, and should be provided with some load capacity rating. The present work presents an attempt to derive Working Load Ratings for the various types of anchor point tested in the previous test program, on the basis of the data obtained from that test program.
